Mold for meat patties

My invention relates to molds such as are used for forming patties from Hamburger or other food materials of similar plastic nature.

5 One object of my invention is to provide a device by means of which patties may, be formed rapidly from plastic meatballs or from the material rolled out into sheet form.

A second object is to provide a device-of 1o .thisnature which may be readily cleaned to 'maintain sanitary condition.

A further object is to provide a device that will produce patties of uniform sha e from either meat balls or from the plastic sheet.

My invention consists in the novel combination of a mold and a plunger faced with foraminous material.

. I have found that with molds commonly used for the urpose specified, that the patty when forme adheres to the mold and especially to the major surface. Various means are employed to overcome this difiicult-y, such as a knife element to separate the plastic from the major surface, a plunger for forcing the patty from the mold, modifications of these means or other means for accomplishing the same purpose. With my invention it is found vthat the plastic material does not adhere to the major surface, as a film of air prevents suctlon v action to retain the plastic major surface in contact with that face of the mold, which in this case is a plunger face, the plunger being adapted to form the enclosed material and to expel it from the mold without adhesion.

The plunger face is formed preferably of wire netting of a mesh which will not permit the material to pass, and a film of air is entrained between the operating surface and the surface of the plunger that'prevent's a normal air pressure acting on the lower surface of the patty unbalanced by a counter pressure on theother face, thus preventing a suction action on the major operating surface.

The patty when forced from the mold, is thus readily released from the plunger without other releasing means.

In the accompanyin specifications and claims, and the drawing forming a part thereof, I have described and illustrated a preferred form of my invention.

. Referring to the drawing,

Fig. 1 is a sectional elevation of a molding device, emboding my invention.

Fig. 2 is a fragmental plan looking in t e u direction of the arrow, and showing the operating face. i

In the drawing, the mold. 10 is formed from a ring. of thin sheet metal secured to the v holder 11. Extending axially through the o0 holder, is a stem 12, rigidly secured at one end to a plunger 13, which is axially and rotatively movable in the mold. I have formed theface of this plunger with grooves 14, and faced it with wire netting 15. This netting is secured in any suitable manner to the plunger, apreferred means being shown as a ring pressed over a flanged portion of the net- The opposite end of the stem 12, is shouldered fat 17, and the outer extension '18 .is threaded to engage the tapped knob 19. Surrounding the stem is a spr1ng-20 reacting onthe-shoulder 21 and the end of the shank 22 of the knob 19, to retain the plunger yieldingly in retracted position in the mold. When the patty is formed the mold may be withdrawn in most cases but should the plastic stick to the sides of the mold, it is only necessary to press on the plunger and force the so patty from the mold when it will release from the plunger without further operation, as no suction action is present. I do not confine myself to this preferred form as modifications may be made within the scope of the appended claims.

Having thusdescribed my invention, I claim:

1. In a mold for forming meat attics and having a plunger axially movab e to expel the patty, the 'coznhinetion therewith of an element formed from wire netting secured to the plunger and constituting the operative major face of the mold. 2.. In a mold for formin meat patties, a plunger axially movable t erein provided with a groovedmajor 'face; an element formed from wire netting secured to and forming the operative face of the plunger, and the major face of the mold.
